2 General

2.1 ApplicationsThe RS232 or RS422/RS485 serial interfaces are available for communicationwith supervisory systems (e. g. bus system or PC). They can, for example, beused to

- read out measurements from the recorder

- read out device and process data from the recorder(for software purposes, the recorder is a device)

- send texts for batch reporting to the recorder

- define measurements and logic signals

2.2 System requirementsThe following items are necessary for operating the serial interface:

- master (e. g. PC or PLC) with the appropriate software

- connecting cable

2.3 Identifying the interfaceThe paperless recorder is supplied with an integral RS232 interface as stand-ard.

Optionally, it can be supplied with an RS422 or RS485 interface (extra code),but in this case without the RS232 interface.

Which interface is implemented in the recorder can be requested via the menuDevice info r Interface 20.

7

2 General

2.4 Communications software PCCWith the help of the PCC software, measurement data that have been saved inthe memory of the paperless recorder can be read out via the serial interfaceor Ethernet. The data can then be comfortably evaluated by the JUMO PCA3000 evaluation software. We recommend using a transmission rate of 38400baud (baud = bps). The baud rate for the paperless recorder is set by the para-meter Configuration r Interface r Baud rate.

The data will now be read out under “timing control”. It is not possible to setup an “online” connection between the PC and the paperless recorder.

2.5 Visualization software JUMO SVS-2000The JUMO SVS-2000 visualization software can be used to read out data fromthe paperless recorder in “online” mode.

2.6 Setup programThe setup program is used to configure the device. It also provides a teleser-vice function for reading out diagnosis and batch data.

HOnly one progam at a time can communicate with the devicethrough each interface. So simultaneous communication is onlypossible by using different interfaces, such as reading out the la-test measurement data via the RS 232/422/485, using JUMO SVS2000, while fetching the saved data from the memory via the Ether-net interface by using JUMO PCC and looking at measurementsthrough the teleservice function of the setup program, via the setupinterface on the front panel.

3 Connecting the interface

3.2 RS232The handshake connections (RTS, CTS) are not used with the RS232 interface.The RTS connection from the master (CTS on recorder) is ignored, the answeris sent directly from the recorder. The CTS connection of the master (RTS onthe recorder) remains open. If the master evaluates the handshake connec-tions, they have to be bridged in the cable.

3.3 RS422/RS485The RS422 and RS485 interfaces are changed over automatically by the pa-perless recorder, according to the type of connection (2-wire or 4-wire connec-tion).

HThe use of a screened and twisted connecting cable is recom-mended.

4 Protocol description

4.1 Master-slave principleThe communication between a PC (master) and a recorder (slave) using Mod-bus/Jbus takes place according to the master-slave principle in the form of adata-request/instruction-response.

The master controls the data exchange, the slaves only have a response func-tion. They are identified by their device address. Up to 255 slaves can be ad-dressed.

4.2 Transmission mode (RTU)The transmission mode used is the RTU mode (Remote Terminal Unit). Dataare transmitted in binary form (hexadecimal) with 8 bits, 16 bits for integersand 32 bits for float values.

Data format The data format describes the arrangement of a byte transmitted. The dataformat can be as follows:

HThe paperless recorder can only operate as a slave,and not as a master.

Master

Slave 1 Slave 2 Slave n

Data word Parity bit Stop bit Bit number

8 bits — 1 9

8 bits — 2 10

8 bits even 1 10

8 bits odd 1 10

11


4.3 Device address The device address for the slave can bet set in the range from 1 to 254 (deci-mal). Device addresses 0 and 255 are reserved.

The address is made in binary form (hexadecimal) in the transfer protocol.

4.4 Timing of the communication

Charactertransmissiontime

The start and end of a data block are identified by transmission pauses. Thecharacter transmission time (time for the transmission of one character)depends on the baud rate and the data format used.

For a data format of 8 data bits, no parity bit and one stop bit, this is:

character transmission time [msec] = 1000 * 9 bits / (baud rate)

For other data formats this is:

character transmission time [msec] = 1000 * 10 bits / (baud rate)

Example

HA maximum of 31 slaves can be addressed via the RS422/RS485interface.

Baud rate [baud] Data format [bit] Character trans-mission time [msec]

38400 10 0.260

9 0.234

19200 10 0.521

9 0.469

9600 10 1.042

9 0.938

12


Timing scheme A data request runs according to the following timing scheme:

The master must not make any data requests within t0, t1 and t2, since, if thisis the case, the recorder will either ignore the request or declare it invalid.

t0 Internal waiting time of the recorder before checking the data re-quest (12.5 — 25msec)

t1 This time depends on the internal processing.The maximum processing time is 350 msec

HA minimum response time can be set in the recorder, under themenu item Configuration # Interface. This preset time is the mini-mum time which will be waited before a response is transmitted(0 — 500 msec). If a smaller value is set, then the response timemay be longer than the preset value (because the internal process-ing time is longer) and the recorder answers as soon as the internalprocessing is completed. A preset time of 0 msec means that therecorder responds with the maximum possible speed.

The minimum response time which can be set is required by theRS485 interface in the master to switch over the interface driverfrom transmitting to receiving. This parameter is not required forthe RS422 or RS232 interface, and should be set to 0 msec.

t2 Waiting time which the master has to keep before starting a newdata request.

on RS232 a minimum of 3.5 times the transmissiontime for 1 character (time depends onthe baud rate)

on RS422/RS485 25msec

13


4.5 Structure of the data blocksAll data blocks have the same structure:

Data structure

Each data block contains four fields:

Slave address device address of a specific slave

Function code function selection (read, write, bit, word)

Data field contains the information:

-bit address (word address)

-bit number (word number)

-bit value (word value)

Checksum recognition of transmission errors

4.6 Distinction Modbus/JbusThe Modbus protocol is compatible with the Jbus protocol. The structure ofthe data blocks is identical.

Slaveaddress

Functioncode

Data field ChecksumCRC16

1 byte 1 byte x byte(s) 2 bytes

HModbus differs from Jbus in the absolute addresses of the data.The addresses of the Modbus are shifted by one compared withthose of the Jbus.

Absolute address Jbus address Modbus address

0 1 0

1 2 1

2 3 2

... ... ...

14


4.7 Checksum (CRC16)The checksum (CRC16) serves to recognize transmission errors. If an error isidentified during evaluation, the corresponding device does not answer.

Calculationscheme

Example 1 Read out counter 2 (current count = 12345).

Data request: Read two words, starting at address 0x57 (CRC16 = 0x771E)

Response: (CRC16 = 0xBB92)

Word 1 und Word 2 result in the answer 12345.0.

Example 2 Poll status of relay outputs.

Instruction: Read one word of address 0x31 (CRC16 = 0xD700)

Response (CRC = 0x7447):

Word 1 means that only output 1 is active.

CRC = 0xFFFFCRC = CRC XOR ByteOfMessageFor (1 to 8)

CRC = SHR(CRC)if (flag shifted right = 1)then elseCRC = CRC XOR 0xA001

while (not all ByteOfMessage processed);

HThe low byte of the checksum is transmitted first.

4.9 Password protectionRead and write access via the Modbus can be protected, but this is not com-pulsory. If access to the device is to be made possible without password pro-tection, then the rights for “Teleservice: read”, “Teleservice: write” and "Enterbatch texts” must be enabled in the recorder, for the “public” user (defaultrights). This can be done through the setup program (Extras menu).

If access to the device is only to be made available after previous transmissionof a password, then the rights for “Teleservice: read”, “Teleservice: write” and“Enter batch texts” must be inhibited for the “public” user (default rights). Thiscan also be set up through the setup program (Extras menu). As a result, it willsubsequently be necessary to write the password of the master or user to theaddress 0x011F via the serial interface, before access will be permitted. Com-munication via the interface is then enabled until a period of 30 seconds pass-es without a Modbus instruction being received.

If an attempt is made to read from or write to the device without having pre-viously transmitted the correct password to the recorder, then the device willrespond with Modbus error code 04.

Access rights will also be checked for attempts to access the device via theserial interfaces or Ethernet. The following rights are relevant for access viaModbus:

Address Contents Right required for:

Read access Write access

0x0000- 0x0026

Device information no right required

Message text no rightrequired

Teleservice:write

0x012B- 0x01F2

Recipe for batch report no rightrequired

Enter batch texts

17


If access to these Modbus addresses is to be made available without a log-in(for a PLC, for instance), then the necessary rights must be defined as default(standard) rights in the recorder. This can be done in the setup software, viathe menu Extras r Password administration ....

The recorder is supplied ex-factory with the right “Enter batch texts” includedin the default rights setting, but the rights for “Teleservice: read” and “Teleser-vice: write” are not included.

If an attempt is made to read from or write to a device without having the cor-responding rights, then the device will respond with Modbus error code 04.

5 Functions

Measurements and other device or process data can be read out from the re-corder using the functions described below.

Overviewof functions

There are no separate areas for bit and word for the system variables. The bitand word areas overlap and can be read and written both as bit area or asword area.

Addresscalculation

The word address is calculated as follows:

word address = base address + variables address

The bit address is calculated as follows:

bit address = word address * 16 + bit number

Example: word address for the measurement of analog input 6:

word address = 0x0035 + 0x000A = 0x003F

Example: bit address of the open-collector output:

bit address = (0x002F + 0x0002) · 0x0010 + 0x0005 = 0x0315

Functionnumber

6 Data flow

6.1 Transmission format

Integer values Integer values are transmitted over the Modbus in the following format:first the high byte, then the low byte.

e. g.: Polling the int-value of address 0x0000 if the value 12 (0x000C) iswritten below this address.Request: 010300000001840A (CRC16 = 0x840A)Response: 0103020019798E (CRC16 = 798E)

Float values Float values are handled on the Modbus with the IEEE-754 standard format(32bits), but with the difference that bytes 1 and 2 are swapped with bytes 3and 4.

Single-float format (32bits) to standard IEEE 754

S - sign bitE - exponent (complement to base 2)M - 23bit normalized mantissa

Modbus-float format

z. B.: Polling the float value of address 0x0035 if the value 550.0(0x44098000 in IEEE-754 format) is written below this address.Request: 010300350002D405 (CRC16 = D405)Response: 0103048000440920F5 (CRC16 = 20F5)

After transmission from the device, the bytes of the float value have to beswapped accordingly.

Many compilers (e. g. Microsoft C++, Turbo C++, Turbo Pascal, Keil C51) re-cord the float values in the following order:

float value

Please find out how float values are saved in your application. If required, thebytes have to be swapped accordingly in the interface program, after acqui-ring them from the paperless recorder.

MMMMMMMM MMMMMMMM SEEEEEEE EMMMMMMM


Address x Address x+1 Address x+2 Address x+3

MMMMMMMM MMMMMMMM EMMMMMMM SEEEEEEE


25

6 Data flow

Texts Texts are transmitted in the ASCII format.

Since texts are also transmitted word by word (16 bits), an additional 0x00 istransmitted when there is an uneven number of characters (including “\0”).

e. g.: Polling text of address 0x0002 if the character string“LS cf ” (ASCII-Code: 0x4C,0x53, 0x20, 0x63, 0x66, 0x20, 0x20, 0x20, 0x00) is belowthis address.Request: 0103000200052409 (CRC = 2409)Response: 01030A4C532063662020200000DDBB (CRC16 = DDBB)

HThe last sign transmitted must always be a “\0” (ASCII code 0x00) asa stop marker.

26

7 Error messages

7.1 Error handling

Error codes If the data request by the master was received by the paperless recorder (with-out transmission error), but could not be processed, the recorder respondswith an error code.Five error codes are available:

1 invalid function

2 invalid parameter address

3 data value outside permissible range of values

4 slave not ready, or no access rights (password)

8 write access denied for parameter

If a bit or word number is read by the master which is larger than the maximumpermitted one, the recorder also sends the error code 2.

Responseon error

The function code is linked by OR with 0x80, i. e. the MSB (most significantbit) is set to 1.

Example Data request: (CRC16 = 1C0B)

Response: (CRC16 = 8650)

Special cases The slave does not respond to the following errors:

- the baud rate and/or data format for master and recorder do not match

- the device address of the recorder does not correspond to the one in the protocol (in this case, the data request by the master has to be sent again after a time-out of 2sec has elapsed).

- the checksum (CRC16) is not correct

- the instruction by the master is incomplete or over-defined

- the number of words or bits to be read is zero

HExternal logic inputs (R/W) and external analog inputs (R/W)can be programmed via the serial interface or connected tothe paperless recorder in the form of modules of the JUMOmTRON automation system.

For additional information, please refer to Chapter 9 “Specialprocess data”, or to the Operating Instructions 70.6570.2.1(LON interface).

9 Special process data

The following chapter describes the special process data in detail:

- external logic inputs,

- Modbus flag,

- external analog inputs and

- texts for batch reports.

The addresses of these process data can be taken from Section 8.2 “Processdata”.

9.1 External logic inputsThe external logic inputs are only available as operating inputs via the serial in-terface when no external mTRON modules are used.

If the logic inputs are operated via the serial interface, although external mod-ules are connected and active, then the data will only be accepted briefly bythe paperless recorder and will be overwritten by the external module shortlyafterwards.

Like other logic signals (e. g. logic inputs or alarms), the external logic inputscan be used to operate different recorder functions. For this purpose, it is nec-essary to select “External input 1 — 6" as the corresponding operating signalin the configuration.

9.2 Modbus flagThe Modbus flag, like other logic signals (e. g. logic inputs or alarms) can beused to operate different recorder functions. In order to be able to use theModbus flag, the entry “Modbus flag” has to be selected when configuring therecorder.

A conceivable application for using the Modbus flag is the activation of batchreports via the serial interface, for example.

9.3 External analog inputsThe external analog inputs are only available for transmitting measurements tothe recorder via the serial interface when no external mTRON modules orPROFIBUS interfaces are used.

If the external analog inputs are operated via the serial interface although ex-ternal modules are connected and active, then the data will only be acceptedbriefly by the recorder and will be overwritten by the external module shortlyafterwards.

The external analog inputs can be used like normal measurement inputs of therecorder. For this purpose, it is necessary to select “External input 1 — 36” ascorresponding operating signal in the configuration.

9.4 Texts for batch reportsFor batch reporting, there are several options for entering texts which can bestored as labels for the batch measurements. One possibility is the transmis-sion of the texts using the serial interface.

The texts can be sent to the paperless recorder via the base address 0x00A6(offset 0x0000, 0x000B, 0x0016, 0x0021). If less than the maximum possiblenumber of characters is sent per text, then the recorder automatically fills thetext with empty spaces and writes 0x00 in the last position.

9.5 Recipe text for batch reportsEach batch report includes 400 bytes for a freely-selectable text that can bedownloaded to the recorder via one of the interfaces. This text forms part ofthe batch report and will be generated together with the report. It cannot bedisplayed on the recorder, only on the PC, in the PCA 3000 evaluation pro-gram.

This text could, for example, be used to save the recipe for a batch.

9.6 Message text for the entry in the event listIf a text is written to the Modbus address for the message text, then it will beentered into the event list in the recorder.

HIn order to send a batch text via the interface, the correspondingbatch parameter (e.g. Batches r Line 1 r Contents right column)must be configured to “from interface” in the device.

If this is not the case and a batch text is sent to a device, then thedevice will respond with the Modbus error code 04.
